Lowering of the sea level resulting in a lack of fish close to coastal communities.
Lowering of the sea level resulting in a lack of fish close to coastal communities.

Rising sea level causing flooding to coastal areas impacting housing and the economy.

Answer 1

Correct choices:
- Lowering of the pH of the oceans resulting in loss of coral reefs. (ocean acidification harms calcifying organisms and reefs, affecting fisheries and tourism)
- Increases in the biodiversity of invasive species. (warming and changing currents allow many non‑native species to expand, which can harm fisheries, aquaculture and ecosystems)
- Rising sea level causing flooding to coastal areas impacting housing and the economy. (sea‑level rise increases coastal flooding, erosion, and saltwater intrusion)

The incorrect choice is the one about lowering sea level — climate change causes sea level rise, not a broad lowering that would reduce nearshore fish.
